Leak Detection in London, Found Without Digging Up the Floor

Leak detection in London: what the price includes

• 01
  Acoustic correlation

  Microphones on the pipework either side of the suspected run listen for the sound a pressurised leak makes, then triangulate the position along it.

• 02
  Thermal imaging

  A hot-water leak under a solid floor shows as a heat plume long before it shows as damp. The camera maps it without lifting anything.

• 03
  Tracer gas

  For the difficult ones: hydrogen and nitrogen introduced into the drained pipe escape at the fault and are detected at the surface. It finds leaks the other two methods miss.

• 04
  Written report for the insurer

  Photographs, position, depth, cause and the repair carried out. Trace-and-access cover exists in most policies but insurers want evidence, and this is the format they accept.

• 05
  Repair on the same visit

  We are plumbers first. Where the leak is reachable once found, it gets fixed there and then rather than booked for another day.

Local conditions we work around

Detection earns its money in London because of what opening up costs. Original plaster, cornicing, marble and parquet in period and listed properties are far more expensive to reinstate than the pipe repair itself, so acoustic tracing, thermal imaging and tracer gas mean we open once, in the right place. In flats there is a second reason: a documented trace establishes whose pipework failed, which is what the freeholder, the managing agent and the insurers all need before anyone agrees to pay.
